Advices / Feedbacks required about a full AMD build

Plex Media Server
1

Hello,

I’m using Plex for at least a decade (on Ubuntu) and I really love it. I’m planning to update my computer for an AMD Ryzen 9 7900X and a new Radeon 7000 serie. Been a Intel/nVIDIA consumer for too long and this generation of AMD is really interesting.

I don’t know if everything will run smoothly on a full AMD build, anyone tried? Any feedback?

Ages ago AMD transcoding wasn’t supported, is it fixed? Are they working on it?

Please, I’m planning to update soon so I need to know if everything will be fine for Plex.

Sorry to state:

No AMD GPU support whether internal to CPU or on discrete GPU card.

Engineering never implemented it.

So no hardware support, my CPU will be used fully for everything… or i take an nVIDIA GPU to help a bit if needed?

Correct.

  1. No hardware acceleration for AMD products
  2. Nvidia is supported (GT-1050 is as low as you dare go)
  3. Intel Quick Sync Video is supported.

And the dev team is not even considering working on it? someone said it was working

At least the CPU hardware support.

Damn, would be so sad if I have to buy a 13900K just for the hw encoding/decoding.

@scoony

IF you are skilled enough at Linux to setup libva, which includes the device ‘driver’ modules for the kernel to access and the VAAPI libraries which support AMD products then yes it works.

The key element here is libva.

You don’t need an intel 12K CPU (AlderLake). I have a simple i7-7700, i7-8809g (NUC8-i7), and an older E5-2690v4 with P2200 and I’m fine. There is no content out there which needs more than 4K resolution

Yes, people talk about AV1 but it’s not in PMS yet. Engineering acknowledges it’s something to do but right now, they’re focused on upgrading the transcoder to support all QSV-capable CPUs native to PMS.

I was so happy to update my server… lol not anymore.

Was planning to make a VM with a dedicated graphic card, was expecting to use the CPU for the transcoding. Was wanting to play and run my Plex server.

Now I don’t know what to do, go with a Ryzen and wait for your team to support the new Ryzen GPU integrated or go for an Intel 13th gen even if it’s the last CPU for the socket 1700.

If I understand properly, I will use about 2000 passmark per 1080p transcode without hardware support from my CPU or a dedicated nVIDIA GPU.

Honestly, are they planning to support the AMD CPUs anytime soon?

  1. ESXi VM or something else? If using ESXi then OK buy any other hypervisor is a total waste as you’ll have an OS abstracted on top of an OS which wastes huge amounts of resources.

  2. They haven’t supported AMD yet … I wouldn’t hold my breath

  3. 2000 Passmarks per 10Mbps of H.264 video. 3500 Passmarks per 10 Mbps of HEVC. Tone mapping adds 2000 Passmarks per stream.

The Linux kernel is barely getting settled with the 12th Gen Intel. You’ll be a while before 13th Gen support is stable. The chip was only announced last week.

Was planning an Ubuntu with KVM + VFIO and Plex installed directly in the Ubuntu (deb).

The VM was just to play on windows :slight_smile:

If:

  1. Native host - Ubuntu / Debian
  2. PMS on the native host OS
  3. Other type 2 (hosted) hypervisor for play purposes

You’ll be fine.
